AWNING- FRAM E.

SPECIFICATION forming part of Letters Patent No. 600,306, dated. March 8, 1898.

Application filed May 19, 1897. Serial No. 637,185. (No model.)

To CLZZ whmn it int/,7 concern:

Be it known that I, NATHAN O. DECKER, of Allentown, in the county of Lehigh and State of Pennsylvania, have invented certain new and useful Improvements in Awning-Frames; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide an improved awning-frame, including particular mechanism that will greatly facilitate the operation of raising and lowering the awning; and to this end the invention consists in providing an awning-frame with a toothed segment which is turned by a sliding rack-bar having an operating-handle spring actuated to engage, a catch which holds the awningin an adjustable position.

In the following specification I have entered into a detailed description of the invention, reference being had to the accompanying drawings, and to numerals thereon, which designate the diiferent parts, and what I consider to be the novel features of construction are specifically set forth in the claims.

In the drawings forming part of this specification, Figure 1 is a perspective View showing the application of my invention, one side of the awning being cut away to show the connection between the operating rack-bar and teeth-segment. Fig. 2 is a detailed perspective view of the awning-frame and operating mechanism therefor. Fig. 3 is a sectional view through the catch which holds the operating-rod in an adjustable position.

Referring to the drawings by numerals, l designates the frame of the awning, which is made up of a rod or bar which is bent into any shape presenting the lower part of the awning, and one end of this bar is pivoted to a bracket 2 by means of a pivot or bearing pin 3, the said bracket having a laterally-extending flange 4, with screw-holes therein, through which the retaining-screws pass for securely attaching the bracket to the windowframe. The opposite end of the rod forming the awning-frame is rigidly secured to a toothsegment 5, mounted upon a transverse pin 6, supported in the bracket 7, which is also provided with a flange, through which the retaining-screws pass.

Immediately above the bracket 7 is secured a fixture 8, presenting outwardly-projecting flanges 9 9, forming guides which embrace the sides of a rack'bar 10 in mesh with the tooth-segment hereinbefore mentioned. This rack-bar is rigidly attached to or formed integral with an operating-rod 11, that extends downward therefrom, terminating in a looped handle 12, an intermediate portion of the said operating-rod having a series of notches 13 at its inner sides.

From the foregoing description it will be seen that the awning-frame can be raised and lowered by sliding the rack-bar through the intervention of the operating-rod, the movement of the rack-bar turning the tooth-segment, which forms part of the said awningframe, andin order to support the awning at any inclination desired I provide a device which engages the notches in the operatingrod. This device consists of a box 14, having a vertical opening in its top and bottom, through which the operating-rod passes, the wall-plate 15 of the box having a projecting lug 16, which engages the rod, the latter being forced into such engagement by means of a helical spring 17, which presses against the outer side thereof. This arrangement or device for holding the operating-rod in an adjusted position acts to normally hold the rod in engagement with the lug, and when it is desired to manipulate the said rod it is only necessary to pull it slightly forward out of engagement with the lug and against the action of the spring, the rod being then free to be slid up or down.

In order to assist the upward movement of the part of the awning-frame opposite the end which carries the tooth-segment, the bracket 2 carries a spring 18, the outer end of which is in engagement with an eye or hook 19, attached to the awning-frame. This spring is of sufficient strength to relieve this part of the frame of its own weight and that of the awning or canvas, in order that when the rack-bar is operated to lift the awning it will not sag at the end opposite that which is acted upon directly by the raising and lowering mechanism.

This improved device for raising and lowering an awning provides a very simple, cheap, and effective means for the purpose, and when itlhelagloarts have been adjusted they are securely The particular device engaging the operating-rod forms one in which the said rod is readily and conveniently released when it is desired to raise and lower the same and is automatically engaged after being operated.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is I 1. The combination with an awning-frame, of a toothed segment secured thereto, an operating-rod, a rack-bar secured to or formed integral with said operating-rod and suitably supported in mesh with the toothed segment, and a device acting upon the operating-rod for positively holding the rack-bar in adjusted position, as and for the purpose set forth.

2. In an awning, the combination with the frame having a tooth-segment forming a support therefor, a rack-bar suitably supported in mesh with the-tooth-segment and having an operating-handle, a device engaging the handle to hold the bars adj listed, and a spring connected to the frame opposite the end which carries the tooth-segment, substantially as and for the purposes set forth.

3. In an awning, the combination with the frame pivoted to the bracket at one end and having a tooth-segment rigidly secured to its other end through which a pivot-pin passes into a supporting-bracket, a fixture presenting projecting flanges or guides, a rack-bar in sliding engagement with the fixtures and in mesh with the tooth-segment, an operating-rod extending from the rack-bar and having notches at its inner side, and a catch engaging the notches of the operating-rod, substantially as and for the purposes set forth.

4:. In an awning, the combination with the frame having a tooth-segment by which it is pivotally supported at one end, a rack-bar meshing with the tooth-segment and having an operating-rod with notches in the rear side thereof; together with a fixture having a stationary lug and a spring which presses upon the operating-rod and forces it normally in engagement with the lug, substantially as and for the purposes set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

NATHAN O. DECKER.
